Time in standard quantum mechanics extends from -infinity < t < + infinity; this is the result of a mathematical theorem (Stone-von Neumann) for the solutions of the Schrodinger equation for states or of the Heisenberg ...

The opener-stretcher motor neuron in crayfish makes 50 endings upon each of 1200 muscle
fibers . We have calculated the quantal content of junctional potentials produced by individual
terminals and by the whole cell at ...

Background: Cell lines have been used to study cancer for decades, but truly quantitative assessment of their performance as models is often lacking. We used gene expression profiling to quantitatively assess the gene ...

The advent of next-generation sequencing has brought about an explosion of single nucleotide polymorphism (SNP) data in non-model organisms; however, profiling these SNPs across multiple natural populations still requires ...

The question of quantum contextuality in the Mermin-Peres square is considered. It is shown that a deterministic, noncontextual hidden variable model of this problem is not inconsistent with quantum mechanics, contrary to ...

The quasar SDSS J105041.35+345631.3 (z = 0.272) has broad emission lines blueshifted by 3500 km s(-1) relative to the narrow lines and the host galaxy. Such an object may be a candidate for a recoiling supermassive black ...

This
paper proposes the use of a quasi-random sequence for the estimation of the mixed
multinomial
logit model. The mixed multinomial structure is a flexible discrete choice formulation
which
accommodates general ...

In the lowest order of approximation quasi-twa-dimensional dynamics of planetary atmospheres and of plasmas in a magnetic field can be described by a common convective vortex equation, the Charney and Hasegawa-Mirna (CHM) ...

We report five new measurements of central black hole masses based on Space Telescope Imaging Spectrograph and Wide Field Planetary Camera 2 observations with the Hubble Space Telescope (HST) and on axisymmetric, three-integral, ...

Introduction: The metastatic progression of cancer is a direct result of the disregulation of numerous cellular signaling pathways, including those associated with adhesion, migration, and invasion. Members of the Rac ...

Kepler-91b is a rare example of a transiting hot Jupiter around a red giant star, providing the possibility to study the formation and composition of hot Jupiters under different conditions compared to main-sequence stars. ...

During the epoch of reionization the 21 cm signal is sensitive to the scattering rate of the ultraviolet photons, redshifting across the Ly alpha resonance. Here we calculate the photon scattering rate profile for a single ...

We carry out high-speed photometry on 20 of the shortest-period, detached white dwarf binaries known and discover systems with eclipses, ellipsoidal variations (due to tidal deformations of the visible white dwarf), and ...

The observed deficit of strongly Ly alpha emitting galaxies at z > 6.5 is attributed to increasing neutral hydrogen in the intergalactic medium (IGM) and/or to the evolving galaxy properties. To investigate this we have ...
